How to access my profile info from facebook in iphone sdk?

How can i fetch my profile information from facebook, using facebook api for iphone sdk. I have successfully able to login using connect method.

after that i have written query something like :

- (void)session:(FBSession*)session didLogin:(FBUID)uid {
    NSString* fql = [NSString stringWithFormat:@"select uid,name,first_name,middle_name,last_name,affiliations,profile_update_time,timezone,religion,birthday,birthday_date,sex,hometown_location,relationship_status,political,current_location,activities,interests,music,tv,movies,books,quotes,about_me,hs_info,education_history,work_history,status,online_presence,family,username,website,is_blocked,contact_email,email,pic_small,pic_big,pic_square,pic,proxied_email,allowed_restrictions,verified from user where uid == %lld",开发者_如何学JAVA _session.uid];

    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];
}

- (void)request:(FBRequest*)request didLoad:(id)result {

    if ([request.method isEqualToString:@"facebook.fql.query"]) {
        NSArray* users = result;
        NSDictionary* user = [users objectAtIndex:0];
        }
}

when i displayed user(Dictionary) i am not able to get all values from my profile. some values which are already exists and set in my profile have been showing as null.

Why i am not able to get all info from my own profile ? or How can i ?

Any idea or help will be well appreciated ?
